Carbon removal, net zero, and implications for Switzerland

Carbon removal, including carbon capture, utilization and storage (CCUS) and negative emission technologies (NET), is an important but small part of climate action, unlikely to scale beyond 5-10% percent of current emissions, in the 2-3 critical decades we ...

Large-scale regionalised LCA shows that plant-based fat spreads have a lower climate, land occupation and water scarcity impact than dairy butter

Xun Liao

Purpose In light of the sustainable diet debate, we conducted a large-scale regionalised LCA to answer the following questions: (i) does the climate advantage hypothesis of plant-based fat spreads and creams over dairy butter and cream hold regardless of t ...

Millennial-scale atmospheric CO2variations during the Marine Isotope Stage 6 period (190-135 ka)

Jérôme Chappellaz

To interpret new high resolution climate records it becomes more and more important to know about the succession of climate events. Such knowledge is hard to get especially when dealing with different types of climate archives. Even for ice cores a direct ...

Concerns of young protesters are justified

Philippe Thalmann, Dominique Bourg

In this letter, we recall that young people's concerns about climate change are based on our best scientific knowledge and that the measures taken so far by our authorities to protect the climate and the biosphere are far from up to the threat. We therefor ...

Understanding climate change from a global analysis of city analogues

Gabriele Manoli, Haozhi Ma

Combating climate change requires unified action across all sectors of society. However, this collective action is precluded by the ‘consensus gap’ between scientific knowledge and public opinion. Here, we test the extent to which the iconic cities around ...

Magnitude of urban heat islands largely explained by climate and population

Gabriele Manoli, Gabriel George Katul, Paolo Burlando

Urban heat islands (UHIs) exacerbate the risk of heat-related mortality associated with global climate change. The intensity of UHIs varies with population size and mean annual precipitation, but a unifying explanation for this variation is lacking, and th ...

Aerosols in an arid environment: The role of aerosol water content, particulate acidity, precursors, and relative humidity on secondary inorganic aerosols

Athanasios Nenes, Yi Wang, Hui Wang, Qianyu Zhao

Meteorological conditions, gas-phase precursors, and aerosol acidity (pH) can influence the formation of secondary inorganic aerosols (SIA) in fine particulate matter (PM2.5). Most works related to the influence of pH and gas-phase precursors on SIA have b ...

Development of N-Type Amorphous and Microcrystalline Hydrogenated Silicon-Oxides (SiOx:H) and Investigation of their Impact as Window Layers on Silicon Heterojunction Solar Cells Device

Christophe Ballif, Mathieu Gérard Boccard, Jan Haschke, Jean Cattin, Brahim Aissa

We report on the development of hydrogenated n-type amorphous and microcrystalline silicon oxides ((n)-SiOx:H and (n) mu c-SiOx:H, respectively) by PECVD, and their successful integration as n-window layers for silicon heterojunction (SHJ) solar cells devi ...

Different approaches to improve energy consumption of battery electric buses

Francesco Baldi

Transportation electrification is increasing and recently more focus has been directed on heavy vehicles and especially on city buses. Battery electric buses are inherently more energy efficient than diesel buses and the efficiency can be further increased ...

Snowmelt-Driven Trade-Offs Between Early and Late Season Productivity Negatively Impact Forest Carbon Uptake During Drought

Ernesto Trujillo Gomez

uture projections of declining snowpack and increasing potential evaporation are predicted to advance the timing of snowmelt in mountain ecosystems globally with unknown implications for snowmelt‐driven forest productivity. Accordingly, this study combined ...
